Pb-Free package is available

The Schottky Power Rectifier employs the Schottky Barrier principle with a

barrier metal that produces optimal forward voltage drop–reverse current

tradeoff. Ideally suited for low voltage, high frequency rectification, or as free

wheeling and polarity protection diodes in surface mount applications where

compact size and weight are critical to the system. This package provides an

alternative to the leadless 34 MELF style package. These state–of–the–art

devices have the following features:

• Guardring for Stress Protection

• Very Low Forward Voltage (0.38 V Max @ 0.5 A, 25°C)

• 125°C Operating Junction Temperature

• Epoxy Meets UL94, VO at 1/8″

• Package Designed for Optimal Automated Board Assembly
